The polar jet stream often plunges southward. When this happens, it can drive cold fronts to regions as far south as Florida. When the polar jet stream plunges south over the United States during the winter time, it is sure that some very cold weather will follow. It changes condensation forms, causes strong storms, thus, transporting cold air.
Virginia has many deposits of sand and gravel since these are found on places where once water flowed. Sand and gravel deposits usually can be found in the rivers and beaches. These are usually used for construction of the roads mix with asphalt.
The correct option is this: IT EXHIBITS A SPECIFICITY FOR A PARTICULAR TYPE OF MOLECULE.
Carrier proteins are integral proteins that are embedded on the plasma membrane of the cells. The proteins help different substances to enter inside the cells. Each carrier protein exhibit specificity in that it carries only a specific type of substance.
Exon one has 570 nucleotides. Exon three has 810 nucleotides. We are not concerned about exon two because it is spliced out in the variant. There are 1380 nucleotides (570+810). Each amino acid requires three nucleotides. One codon, or three nucleotides, codes for one amino acid. So 1380/3=690 amino acids.
Answer:
The correct option is C.
repaying an oxygen debt.
Explanation:
This is because while running, humans breath shallowly which could not provide the oxygen requirement for the respiratory system and fit in for blood need.
After running, you tend to breathe heavily because your muscle work very hard , the body use more oxygen and produced more carbondioxide, therefore the lungs and respiratory system must try to provide more oxygen to the blood. sympathetic nerves stimulate respiratory muscles
so as to increase the rate at which we breathe.
